Patented Dec. 25, 1906.

To all whom it may concern:

Be it known that I, ALLEN DE VrLBIss, Jr., a citizen of the United States, and7 a resident of Toledo, Lucas county, State of Ohio, have invented certain new and useful Improvements in Computing-Scales, (Case No.,

33;) and my preferred manner of carrying out the invention is set forth in the ,following full, clear, and exact description, terminating ith claims particularly specifying the noveity.

This invention relates to scales of that class which compute or indicate the total weight and total price, preferably by means `of a cylinder rotating on its axis within a casing which is provided with openings at suitable points to permit the dealer and the customer to see through them the results which it is desired shall be indicated; and the obinvention is to construct a whose indicating mechanism, comprising the cylinder and the slotted casing, is combined. with weighing mechanism substantially of the character covered by patents hitherto issued to me on this line of mventlon. n To this end the, present invention consists in a construction of parts which 'shall adapt the indicating mechanism, above described, and the weighing mechanism to joint use in `the simplest manner and whereby all necessary adjustments are permitted.

The following speciiication describes'my preferred manner of carrying out the invention, whereas the claims embrace the salient points or combinations of elements, all as illustrated in the accompanying drawings, wherein- Figure I is a sidelevation of the weighing mechanism and a sectional vie'w of the indieating mechanism. Fig. II is a plan view of this scale with the platform removed and .the casing shown in section on a line through the main pivot. Fi III is a lon itudinal sectional view of the body portion o? the casing with its drum-shaped housing partly broken away, so as to show the cylinder in elevation therein.

1 is the main scale-beam, fulcrumed at 2 on a support which rises from the base, and 3 is a pan or platform having a standard 4,

ivotally supported, asv at 5, upon said beam. T e base supports a casing consisting of an 9 at its lower end.

upright body portion 128 arearward extension 129) and a drumeshaped housing 130 at has openings 131 pear below.,

6 is a disk having knife-edge bearings 7, supported upon blocks 70 within the body portion of the casing, and from this disk hangs rigidly a pendulum 8, having a weight The scale-beam 1 is diverted from a straight line, as best seen at 100 in Fig. II, so that within the body portion of the casing it passes completely around the disk and the parts attached thereto and returns again to the line of its body, and at its extreme end a link 11 leads upwardly from this beam and is connected as by knife-edges, with a link-pivot 10, here shown as an arm projecting radially from the disk 6. From the latter, diametrically opposite the link-pivot, projects a counterbalance-arm 17, carrying a weight 18, the latter being sufiiciently remote from the center 7 andof suiii cient weight to counterbalance the weight of the link-pivot, the link, that end of the main beam, the pan or platform, and the connecprovided with its top, which tions hereinafter described by means of which the indicating mechanism 1s moved.

As indicated in section in Fig. II, the arm 17 may be a screw and the weight 18 adjustable thereon, and I will hereinafter speak of this arm as'a screw In connection with a scale of the above type I preferably use indicating mechanism such as will now be described. Pivoted at 90v to the main beam is a fork 91, which eX- tends upwardly and thence outwardly and then again upwardly into two arms 92, which (preferably having and 132 for a purpose to ap- 'are toothed, so that they constitute rackj bars. These vengage the teeth of gears 93, mounted fast on the shaft 94 of the cylinder 95, rotatable within the housing 130; but it will be clear that any other suitable form of ing an upward movement of the main beam 1 into a rotary movement of the cylinder. Herein where I speak of the devices shown as connections for this urposel desire to be understood as includin any'equivalent devices for accomplishing t 's end.

The face of the cylinder is inscribed with a table 13, and in the present instance there are two bands around this cylinder, which connections might be employed for convert- IOO . front side of the housing adjacent the dealer l f is a"row of figur prices pei-pound, and the table 13 on the cyl-v es 192, giving the various inder carries the total prices, which arebso arranged thereon as to comeuiider their respctive prices per pound and b observable t ough`` the opening 132 when the proper vweight-total 14 comes opposite the pointer 133. I do not-limit myself to this exact arrangement; but I prefer itin scales of this ty e. v

Ii`he operation is as follows: The commodity being placed upon the pan or platform 3, the outer end of the scale-beam 1 descends and through the link 11 causes a rotation of the disk 6 on its pivots 7, drawing the link pivot-arm 10 -downwardly from its normal position, which is above that of the nain pivot 7. This swings the weight 9 to the right, as indicated by the arrow, and lifts the counterbalance-weight 18 vand the fork 91. I repeat that said weight 18 is of Suficient size and so ad'usted on the screw 17 as to exactly counter alance all parts of the' scale when. the latter is at rest. The pendulum 9 rises in proportion to the weight of the commodity, and the rack-bars. 92 turn the gears '93 and rotate the cylinder 9 5 on its axis 94, as wlll be clear.

The row 140 of Weight-totals assing under the opening 131 is exposed to t e customer, who may see that heobtains full weight, and meanwhile the row 14 of weight-totals passes under the.poi nter 133 and gives the same information to the dealer.y

With. the present construction, however, that longitudinal row on the table 13Which ,corresponds to the total wei ht comes opposite the opening 132 on the ealers side of the housing, and under the proper iigure in the row 192' indicating theprice per o und h e can uickly see the tota price. t 1s obvious t at this arrangement of openings could be modified to some extent without departing from the spirit ofmy invention. The parts are ofthe desired sizes, shapes, proportions, and materials, and the invention ma beused with or without other details Whic form no feature of the present case.
